TIRE-CHAIN' FASTENER.

Specification of Letters Patent.. Pittiltd Aug, 22, 1922.

Application led January 23. 1822. f Seria1`No.`531,0"/1.

ject is to provide a simple, efficient and practical construction of fastener which, When properly applied to a chain on a vehicle Wheel, will securely hold the ends thereof together and will not accidentally become unlocked so that the chain can be lost. Additional objects will be disclosed in the course of the following specilication and are illustrated in the` accompanying drawing,y in which: y

Fig. l is a side elevation of my improved tire chain fastener, illustrating the manner in which the same is applied to a chain.

Fig. 2 is a detail sectional elevation of.

the device as seen inv Fig. l, butvvith the near side portion of the body kmember proper and the chain removed.

` Fig. 3 is an elevation of the fastener, as seen in Fig. l, but showing it. as open.

Fig. 4 is a top plan view seen in Fig. l.

Referring now by reference characters to the various figures in the drawing A designates 'a block having tivo spaced integrally formed side plates Bibetween which operates a lever C, the sameturning on a pivot pin D. The block A is provided with a T- shaped notch E and the lever C is provided Withwa T-shaped notch F. One end link fr" of the tire chain is secured to one end of the block A by a pin H, While the link J at the other end of the chain hooks into the notch F when the fastener is open, and when it is closed said link engages in both of the notches E and F. It may here be noted that when the fastener is open (see Fig.` 3) the openings in the slots E and F both extend in the same direction, but when the fastener is closed said openings extend in opposite directionsso that the link J can-- not possibly escape untilthe lever C is again swung open. lt may also be noted that when the fastener is closed the left end lof the slot F is slightly shorter than the corre'- sponding end of the slot E. yThis causes thel link J to pull on the lever C and thus tends of the device as y the .lever `get open, as in Fig. 3, the link yJ lto hold itfsecurely locked. The other end of the slot F is long enough sothat, should .60V

can just pass over the corner K and -vvill-y ithere remain secure, to a certain extent, 4from i escapement Vfrom the lever notch F'. The plates B are provided with corresponding recesses L so that the lever,iivhen closed, can be gripped by the fingers or a pairfof pliers. .y The lever itself may be provided withy a shall groove M under which an instrument may engage to pry the lever out, if vnecessary.

it is understood that, ent disclosure is believed to be the preferred embodiment of the invention, it is not limited thereto, andthat various modifications and changes may be made therein, if Within` the Aspirit and scope of the appended claims.

Having nebtv therefore fully shown and although the pres-` described my invention, what I claim to be ber,v including spaced plate portions inte` grally formed at one end, a lever pivoted bet lever having longitaidinal` slots and passages leading thereto' adapted to receive', a chain neiv and desire to protect by Letters Patent 'i A' lJKA fastener consistingof a body mem- 'een said plate portions,'said body and link when the lever is in open position and lock the linkin the fastener vvhenl in closed j-.ies'1.ti.on, said slot inthe lever being .slightly 90 shorter at its fore-end than the corresponding slot in the body member so as tor bringthe `tress of said link primarily on the lever.

Q1. fin member having a notchvin its upper edge, a lever pivo'tally secured 1n said body member,

said lever' having a T-shaped notch inl one edge thereof, said notches forming a'closedl slot in the fastener when the leverA is closed,

' the notch in said lever` extending far` enough from its pivot to allow a link engaging therein to pass an upper end corner of lsaid body member.

In a fastener, a ini; two spaced4 plate portions' connected at onev end, va lever pivotally secured between said plate portions near thev other end and near one edge of the body member, said lever and plate portions Ahaving "i'shaped v notches opening at opposite edges of the respective members, so that when the fas.-v tener is closed ,said notches formy a closedv slot therein.

In'testimony'whereof I affix` inv si nature.
